Procedure E
If the green NORMAL indicator is off, the yellow TROUBLE indicator is on, and the BAT OPEN indicator on the SABC module is on,
a battery trouble condition has occurred. A battery trouble condition may be caused by:
1.
A fuse on the SABC module is blown.
2.
Faulty field wiring to batteries.
3.
A faulty SABC module.
Perform the following:
1.
Verify that all fuses on the SABC module are intact.
2.
Verify that the field wiring to the batteries is intact.
3.
Replace the SABC module.
Procedure F
If the green NORMAL indicator is off, the yellow TROUBLE indicator is on, and the AMP indicator on the SAA module is on, an
amplifier trouble condition has occurred. An amplifier trouble condition may be caused by:
1.
Faulty internal wiring between the backplane module and the digital voice module.
2.
A faulty SAA module.
3.
A faulty SADC module.
4.
A faulty backplane module.
Perform the following:
1.
Verify that the wiring between the backplane module and the digital voice module is intact.
2.
Replace the SAA.
3.
Replace the SADC module.
4.
Replace the backplane module.
Procedure G
If the green NORMAL indicator is off, the yellow TROUBLE indicator is on, and the SPK indicator on the SAA module is on, an audio
output wiring trouble condition has occurred. An audio output wiring trouble condition may be caused by:
1.
Missing end-of-line resistor on the audio output.
2.
The audio output field wiring is open or shorted.
3.
A fuse on the SAA module is blown.
4.
A faulty SAA module.
5.
A faulty backplane module.
Perform the following:
1.
Verify that the end-of-line resistor is properly in place.
2.
Verify that the audio output field wiring is intact.
3.
Verify that all fuses on the SAA module are intact.
4.
Replace the SAA module.
5.
Replace the backplane module.
Procedure H
If the green NORMAL indicator is off, the yellow TROUBLE indicator is on, and the STR indicator on the SAA module is on, a visual
notification output wiring trouble condition has occurred. A visual notification output wiring trouble condition may be caused by:
1.
Missing end-of-line resistor on the visual notification output.
2.
The visual notification output field wiring is open or shorted.
3.
A fuse on the SAA module is blown.
4.
A faulty SAA module.
5.
A faulty backplane module.
Perform the following:
1.
Verify that the end-of-line resistor is properly in place.
2.
Verify that the visual notification output field wiring is intact.
3.
Verify that all fuses on the SAA module are intact.
4.
Replace the SAA module.
5.
Replace the backplane module.
